The cover picture shows gold nanoparticles encapsulated into a 3D self-standing macroporous hy
drogel made of cross-linked ferritin by dynamic templating. The bionanocomposite hy
drogel exhibits catalytic properties for both nitroaldol and nitroreduction reactions in aqueous solution at room temperature. The findings provide a simple strategy for the development of a variety of biohy
drogel-based nanoreactors. More details can be found in the Full Paper by David Díaz Díaz et al. on
